The amino acid sequence is the primary structure of a protein and it is unique to a particular peptide or protein. Determining amino acid composition in protein/peptide hydrolysates, foods, feeds, and pharmaceutical preparations is important. Amino acids are also key ingredients in the cell culture medium used to prepare recombinant proteins. It is often desirable to monitor on a regular basis the consumption of individual amino acids reaction in the bioreactor so the conditions in the bioreactor can be optimized.
Accurately separating, identifying, and quantitating amino acids is challenging. Waters provides a number of solutions that use pre-column derivatization so that amino acids can be easily analyzed. Kits are available in both manual and automated configurations.

Manual OptionsAccQ•Tag Ultra and AccQ•Tag chemistries are the first step in enabling your laboratory to obtain accurate amino acid composition from protein/peptide hydrolysates, physiologic fluids, feeds, foods, pharmaceutical preparations, and many other sample matrices. Combined with traditional HPLC, UHPLC, or the Waters ACQUITY UPLC, you can now have a system that is customized to separate amino acids from protein hydrolysates, cell culture media, and food/feed samples to get enhanced resolution. The end result is reliability with precise qualitative and quantitative results. AccQ•Tag Ultra and AccQ•Tag chemistry kits include:

Application: Food and FeedsAnimal feeds pose several significant challenges for accurate amino acid analysis. Quantitation of amino acids released by hydrolysis is one important measure of nutritional value. A free amino acid profile can identify the origin of a food product, and in that way, detect adulteration. Free amino acids are also metabolic indicators that can be used to monitor and optimize processes such as fermentation.
